Homework Help: Uncertainty question

  1. Aug 1, 2007 #1
    Is there a standard way of quoting uncertainties for say counting radioactive decay counts?

    I know I can use sqrt(n)

    And I know I can use fractional uncertainty 1/(sqrt(n)) too.

    Is there a standard way of quoting? Apologies if this is in the wrong section

    Average +/- standard deviation in the mean

    round the standard deviation in the mean off to two significant digits and the average to the same least significant digit as the standard deviation.
